Root Cause Analysis

 Root cause analysis 

 

What is root cause analysis? 

Root cause analysis is the process of discovering the root causes of problems to identify appropriate solutions. Root cause analysis it the thought of that it’s more effective to prevent the issue rather than tackling it when the issue arrives. 

 

 

5 Whys 

The 5 whys are used to explore the relationship between the cause and effect of a problem. The main goal of the 5 whys is to find the root cause of a problem by repeating the question “why?”. Once you’ve got to the last of the why’s, that’s when you’ve found the root cause.  


The 5 why’s could be: 

  • Why is it happening? 

 

  • Why is that? 

 

  •  Why is that? 

 

  • Why is that? 

 

  • Why is that?

Fishbone diagram 

A fishbone diagram is a visual way to look at cause and effect. Compared to other tools to find for finding causes of a problem, like the 5 whys, it is a more structured approach. The problem is often found at the mouth of the fish diagram. Scenarios where a fish bone diagram may come in handy may include, product development and troubleshooting processes. The centre of the fish, (the bone structure), is the place where the brainstormed ideas are held. These could consist of anything from the methods they could use, the budget they have, the machinery they have access to.  

 

 

 

 

 

 


Failure mode and effects analysis (FMEA)

Failure mode and effects analysis (FMEA) is a structured way to identify and address potential problems. This is one of the most basic forms of root cause analysis. It also estimates the potential severity or impact of a root cause analysis (affect). It is a basically a step-by-step approach for collecting knowledge about possible points of failure in a design, manufacturing process, product or service. Many people use FMEA daily. This is when people plan to do, design or make something and they look for potential failures in the process. 

 


Event tree analysis (ETA)

Event tree analysis (ETA) is a procedure that shows all possible outcomes resulting from an accidental event, considering whether installed whether installed safety barriers are functioning or not. An event tree considers the impact of the failure of a particular component or item in the system and works out the effect such a failure will have on the overall system risk or reliability. 

 


Pareto chart 

A Pareto chart is a type of chart that contains both bar and line graphs, where individual values represented in descending order by bars, and the cumulative total is represented by the line. 

 

Scatter Diagram 

A scatter diagram or scatter plot is a type of chart used to show a trend in various sectors of the project. A scatter diagram is plotted against 2 mathematical values on to a 2D graph. A scatter diagram can also show any anomalies and anomalous trends to find the root cause of problems and improve the necessary areas. 

 

 

 

 

When is root cause analysis used? 

Root cause analysis is used to break down a problem into multiple different smaller parts to find the finer causes which could be the root cause. Businesses will use this to find the root cause of a problem. It will help their business become more efficient and effective when dealing with problems and overall productivity.

Topologies

 Topologies What is a network topology? A network topology is the arrangement of the elements, such as links and nodes, of a communication network. Network topology can be used to define or describe the arrangement of various types of telecommunication networks, including command and control radio networks and computer networks.  Network topology examples Point to point topology -      This is arguably the most basic topology as it only consists of 2 nodes and a connection between them. So for example, if you were to configure a router in London, to connect and use resources on a network in Manchester, you would want to make sure that you had a link between them that supports your needs.  Star topology - A star topology is a centralised topology consisting of multiple nodes and a central hub/switch. It is also a design where all devices are connected to a central hub or switch, and messages are passed to the central core that, in turn, passes the

Emerging technologies allowing adaptability and future proofing

  Emerging technologies allowing adaptability and future proofing Machine Learning Machine Learning is a field of study in artificial intelligence concerned with the development and study of statistical algorithms that can learn from data and generalise to unseen data, and thus perform tasks without explicit instructions. Advances in the field of deep learning have allowed neural networks to surpass many previous approaches in performance.   Artificial Intelligence (AI) Artificial Intelligence is a set of technologies that enable computers to perform a variety of advanced functions, including the ability to see, understand and translate spoken and written language, analyse data, make recommendations and more.   Internet of things (IoT) The internet of things refers to a network of physical devices, appliances and other physical objects that are embedded with sensors, software and netw...
